    摘要: When viewed from the upper face of a cylinder head (52A) in which an intake port (10A) communicating with a combustion chamber (54) of an internal combustion engine (50A) is formed, a starting point (Pl) of the port (10A) is defined as a point of intersection of the streamline of the intake port (10A) and an inlet-side opening plane of the intake port (10A) as projected on a horizontal plane (S), and an end point (P2) is defined as a point of intersection of the streamline of the port (10A) and the center -axis of an intake valve (55) as projected on the horizontal plane (S). The starting point (Pl) is located closer to the center of the chamber (54) than a straight line (L2) that contains the end point (P2) and extends in a direction orthogonal to the axis of the crankshaft on the plane (S), and the streamline (F) of the port (10A) projected on the horizontal plane (S) is curved toward the center of the chamber (54), with respect to a straight line (L1) that contains the starting point (P1) and extends in a direction orthogonal to the axis of the crankshaft on the plane (S).

    摘要: The object of the invention is to provide such valve structure that it is easy to introduce, for even an overhead-valve engine, a cylinder head in which the combustion chamber is hemi-spherical. The inlet valve 3 and exhaust valve 2 are positioned in such a manner that they incline substantially like a "V" in front view. Positioned on an inclined plane Ul are the longitudinal center lines 2a, 4a and la of the inlet valve 2, the associated push rod 4 and the rocker arm 1, which connects these, respectively. Positioned on an inclined plane U2 are the longitudinal center lines 3a, 4a and 1a of the exhaust valve 3, the associated push rod 4 and the rocker arm 1, which connects these, respectively.

    摘要: An inlet-valve arrangement is for an external-heat engine, which includes at least one working chamber, each one having a cooperating piston. The working chamber is supplied with a working fluid via at least one controlled poppet valve. The poppet valve is arranged to open in the opposite direction to the flow direction of the working fluid. The center axis of the poppet valve is arranged perpendicularly within a deviation of ±45 degrees relative to the center axis of the piston.

    摘要: An engine (20) provided in a lower part of a motorcycle (100) is arranged such that an axis (CL1) of its cylinder (SI) extends in a front-and-rear direction (Y-direction) of the motorcycle (100). Furthermore, the engine (20) is arranged such that an intake port (Pa1) and an exhaust port (Pb1) in the engine (20) line up in a right-and-left direction (X-direction) of the motorcycle (100). An intake system (50a) and an exhaust system (50b) in the engine (20) are respectively curved toward one side and the other side in the right-and-left direction (X-direction) around the axis (CL1) of the cylinder (SI).
